Gradient Heat Seal Tester

Product catalog summary

Overview
The PARAM® GHS-03 Gradient Heat Seal Tester is designed to evaluate the heatsealability of various films and coated papers under specific conditions of sealing speed, pressure, and temperature. It is particularly useful for determining the optimal heatsealability parameters by considering factors such as melting point, thermal stability, fluidity, and thickness.

Professional Technology

Utilizes digital P.I.D temperature control for rapid and stable temperature achievement.
Offers a wide range of control over temperature, pressure, and time to accommodate diverse testing conditions.
Features manual or pedal switch control and an anti-scald design for safe operation.
Controlled by a micro-computer with an LCD and PVC operation panel for user convenience.
Capable of testing five specimen groups at different temperatures simultaneously.
Equipped with individually controlled upper sealing jaws and easily replaceable heating tube joints.
Includes a micro-printer for data saving, exporting, and printing.

Test Standards
The instrument complies with ASTM F2029, QB/T 2358, and YBB 00122003 standards.

Applications

Basic Applications: Suitable for films with smooth surfaces, including various plastic and composite films, and can perform sealing at five different temperatures.

Catalog excerpts

PARAM® GHS-03 Gradient Heat Seal Tester GHS-03 Gradient Heat Seal Tester is professionally designed for the determination of heatsealability of plastic films, composite films, coated paper, and other sealing films under certain sealing speed, pressure and 5 different temperatures. The heatsealability of heat sealing materials would be greatly affected by the factors of melting point, thermal stability, fluidity and thickness. The properest heatsealability parameters could be obtained accurately and efficiently through this instrument. Professional Technology Digital P.I.D temperature control technology ensures preset temperature to be reached rapidly without any fluctuation. Wide range control of temperature, pressure and time could meet various test conditions.
